Pages and sheets

Before we dive into the details we want to define the difference between a ‘page’ and a ‘sheet’. There seems to be no universal definitions to these words when it comes to describing physical notebooks, but they are important to us to accurately explain specifications. So we defined these words ourselves:

  • Sheet
    The (re)writable surface itself, having 2 sides.
  • Page
    A single side of a ‘sheet’. So 1 side.
  • So:
    2 pages = 1 sheet

Duratech3™ and regular copy paper

Modubooq has a very unique rewritable surface that we named ‘duratech3™’. Below you can see how duratech3™ sheets compare to copy paper:

  • 3 duratech3™ sheets ≅ 10 copy paper sheets.
